FOOT-'LIFT FOR SULKY-PLOWS.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed July 24,1903. Serial No. 166,810.

To all whom t may oon/cern:

Be it known that we, GEORGE ALGER PEN- NOCK and vWILLIAM E. JOHNSON,citizens of the United States of America, and residents of Rock Island,Rock Island county, Illinois, have invented a certain new and usefulImprovement in Foot-Lifts for Sulky-Plows, of which the following is aspecification.

Our invention contemplates an improved foot-lift for use .in connectionwith sulkyplows of various constructions.

It is adapted more particularly for use in connection with sulky-plowsof that type in which provision is made for adjusting Orcontrolling thelandside-wheel independently of the balance of the machine.

Generally stated, the obj ect of our invention is to provide a simple,improved, and highly-efficient foot-lift.

A special obj ect is to provide an improved foot-lift so constructed andarranged that the foot-lever will remain in a horizontal or practicallyhorizontal position from the time the foot is placed upon it until thelandsidewheel assumes the desired position relatively to the balance ofthe machine.

Another Object is to provide an improved construction and arrangementwhereby a parallel motion may be utilized in a practical and efficientmanner for maintaining the footlever in the said horizontal orpractically horizontal position during the independent manipulation ofthe landside-wheel.

It is also an object to provide certain details and features ofimprovement tending to increase the general efficiency andserviceability of a foot-lift arrangement of this particular character.

To the foregoing and other useful ends our invention consists in mattershereinafter set forth and claimed.

In the accompanying drawings, Figure l is a side elevation of asulky-plow equipped with a foot-lift arrangement embodying theprinciples of our invention, the plow being shown in working positionrelatively to the wheels. Fig. 2 is a plan of the plow shown in Fig. l'.Fig. 3 is a view similar to Fig. l, but showing the plow raised out ofthe furrow. Fig. 4 is a detail sectional view 0f the connection betweenthe crank-shaft and spindle of the landside-wheel. Fig. 5 is a detailcrosssection on line 5 5 in Fig. 4.

The plow with the exception of the footlift arrangement can be of anysuitable known or approved construction, For eX- ample, as illustrated,it may comprise a plowbeam A and a plow B of the usual form andconstruction. The plow and beam can be supported by front and rearfurrow-wheels O and D and by a landside-wheel E. The front furrow-wheelcan be mounted on the outturned lower portion of a vertically-arrangedstem c, which is adapted to turn in a bracketbearing d, secured to theplow-beam. This bracket bearing or sleeve is adapted to slide up anddown upon the said stem. The tongue c2 is preferably secured to theupper end of the stem c. As a means for raising and lowering the sleevec upon the said stem so as to raise and lower the plow the machine canbe provided with a hand-lever F, which is secured at its lower end tothe horizontally-arranged crank-shaft G and which is connected with thesleeve c through the medium of a link f and a rock-shaft f. The saidrock-shaft is provided with two arms f2 and f3, the former having itsfree end connected with the said link f and the latter being connectedwith the upper end of the stem c through the medium of a link f4 and acasting f5. It is through the medium of this casting f 5, having ahinge-jointe: with the tongue, that the latter is connected with thestem c. Thus when the said lever is swung about its axis it causes arocking motion of the rockshaft f and a consequent vertical slidingmovement of the sleeve c/ upon the stem c. This of course carries theforward end of the said beam up or down, according to the direction inwhich the lever is swung. The rear furrow-wheel D is preferably in thenature of a caster-wheel. As such it is mounted upon therearwardly-extending lower portion of a caster-stem d, which latter ismounted to turn or oscillate in a bearing-sleeve d. In order that therear portion of the plow-beam and the plow may rise and fall relativelyto this rear furrow-wheel or caster-wheel, the said sleeve d ispreferably connected with the said plow-beam by means of upper and lowerlinks d2 and d3, said links having their IOC forward ends pivotallyconnected with the that all three wheels can be siimiltaneouslyplow-beam and their rear ends pivotally connected with ears on thesleeve d. One of the upper of said links is preferably of the nature ofa bell-crank, being provided with a rear downwardly-extending arm d4.This arm is connected, by means of a link d5, with a stubarm d6 on thelower end or hub portion of the said hand-lever. In this way the saidlever when swung about its axis will cause the said bell-crank to eitherlift or lower the plow relatively to the rear furrow-wheel, according tothe direction in which it is swung. When the said lever F is pulled backand toward the driver's seat H, the plow will be lifted bodilyrelatively to the front and rear furrowwheels. Tt will be observed atthis junction that the said seat is mounted upon the sleeve cZ, andhence that the weight of the driver is suitably sustained by the rearfurrow-wheel.v

In order that the tongue c/l may exert a certain amount of control overthe rear furrowwheel as well as the front iirrow-wheel, the casting f5is preferably provided with a hori- Zontally and traversely extendingslot f6, adapted to receive the upturned forward end of a rod f 7 thelatter having its rear end suitably connected with a laterally-disposedcrank-arm i7 on the upper end of the stem d. Thus the tongue holds thestem d against turning or oscillating in its bearing while the machineis running straight ahead, but allows the said stem to turn and permitthe rear furrow-wheel to swing freely from side to side when the courseof the machine is altered as, for example, in turning around.

The landside-wheel E is preferably mounted on a spindle e, the latterbeing mounted at the end of a casting or crank-arm e. This casting orcrank-arm is loosely mounted on f the crank-shaft G, which latter ismounted to turn in a bearing g, secured to the plowbeam. The hand-levere2 is preferably rigidly secured to or made an integral part of thecasting or crank-arm e. The toothed rack e3 is adapted to be engaged bythe locking-bolt e* on the said hand-lever e2 and is rigidly secured tothe said shaft G. Thus when the said hand-lever and rack are lockedtogether the crank-arm e/ is locked against turning relatively to theshaft G; but by disengaging the said lever from its rack the spindle e,upon which the landside-wheel is mounted, can then be utilized as afulcrum about which to swing the lifting-lever composed of therigidly-connected arm e and lever e2. A backward pull on this lever willobviously lift the crank-shaft and plow-beam, or, in other words, causea relative downward swing on the part of the spindle e about thecrank-shaft as an axis. In other words, the landside-wheel can be givenan independent manipulation by simply pulling back on the lever e2 afterthe same has been disengaged from the rack e3. It is also obviouscontrolled or adjusted relatively to the plow and beam by disengagingthe lever F from its rack fs and by then rocking the crank-shaft G inits bearings.

In order that the driver may use his foot for assisting in lifting theplow out of the furrow, a foot-lever I is preferably mounted upon thesaid spindle e, so as to turn :freely thereon, and is provided with adownwardlyextending arm t. Thus formed the said footlever is in thenature of a bell-crank having a rear portion i, upon which the drivermay conveniently place his foot to assist in raising the plow@ out ofthe furrow. In order that the said foot-lever may serve in the capacityof a lever with the spindle e as a fulcrum., its arm t' is preferablyconnected with the lower arm Z of the rack e by means of a link if. Ttwill be seen that the distance from the center or axis of the saidspindle to the center or axis of the shaft G is the same as the distancebetween the points of pivotal connection of the opposite ends of thelink t2 with the arm i and the lower end of the rack e3. T hus the linki2 and the casting or crank-arm e are adapted to constitute theat-all-times parallel members of a parallel-motion connection betweenthe landside-wheel and the plowbeam. In other words, the members i2 ande constitute the horizontally-disposed elements of what may be termed aparallelmotion connection, and the members i and 2 constitute thevertically-disposed elements of said connection. Tith this arrangementthe lever F when released from its rack can be pulled back so as toraise the plow and beam, and the driver can employ his foot forassisting in this operation by bearing down on the rear end of the leverI. In other words, the spindle e will act as a fulcrum about which totilt a lever, the long end of the lever being adapted to be grasped bythe hand, while its short end is adapted. to be engaged by the foot ofthe driver, but when the plow is in working position and. it becomesnecessary or desirable to wing the plowthat is to say, to keep thebottom level while working on a side hill, for example, or while thelandside-wheel is running over an obstruction-then the landside-wheelcan be controlled independently of the balance of the machine bymanipulating the lever e2, and the advantage of the parallel-motionconnection. lies in the fact that while thus manipulating thelandside-wheel independently of the balance of the machine the footleverI will retain its horizontal or practically horizontal position from thetime the driver starts to move the lever e2 until the plow is given thedesired position. This, of course, and as will be clearly understood isdue to the action of the parallel motion, the connection causing the armfi to remain parallel with the arm z on the bottom of the rack. In

other words, the foot-lever will maintain its horizontal position aslong as the position of the rack e3 remains unchanged. This is of greatadvantage in a foot-lift of this'character, as it enables the driver toadvantageously and conveniently employ his foot for assisting inmanipulating the landside-wheel relatively to the plow and beam. Forwhen the landside-lever is manipulated for the purpose of rocking theplow or lifting up or winging, which is usually accomplished by throwingthe lever either forward or backward, as the case may be, thisparallel-motion connection maintains the foot-lever in its horizontal orpractically horizontal position. When the plow is raised from theground, which is'accomplished by pulling back on the lever F, thefoot-lever then, of course, swings in a downward direction, theparallel-motion connection, the crank-arm, and the crankshaft at suchtime being maintained in a rigid condition and having no movementwhatever relatively to each other. The parallelmotion connection makesit possible to manipulate the landside-lever without effecting theavailability of the foot-lever as a means for assisting the lever F inraising the plow from the ground. No matter what is done to thelandside-wheel independently of the balance of the machine it will beseen that the foot-lever is always ready and in proper position to beengaged by the drivers foot.
